在window7中。进入命令行cmd模式，输入set到多个系统文件夹定义:

比如:

Win7下:

APPDATA=c:\users\xxx\AppData\Roaming

LOCALAPPDATA=c:\users\xxx\AppData\Local

USERPROFILE=c:\users\xxx

ALLUSERPROFILE=c:\ProgramData

HOMEPATH=c:\users\xxx

TEMP= c:\users\xxx\AppData\Local \Temp

TMP= c:\users\xxx\AppData\Local \Temp

Xp下:

APPDATA=c:\ Documents and Setting\xxx\Application Data

无 LOCALAPPDATA

USERPROFILE= c:\ Documents and Setting \xxx

ALLUSERPROFILE=c:\Documents and Setting\Allusers

HOMEPATH=c: \Documents and Setting\xxx

TEMP=c:\DOCUME~1\xxx\LOCALS~1\Temp

TMP= c:\DOCUME~1\xxx\LOCALS~1\Temp

说明:

APPDATA-软件使用时用户的配置信息通常写到此

LOCALAPPDATA-暂时文件夹通常创建到这里

ALLUSERPROFILE-通常软件的鉴权信息写入到

HOMEPATH-用户文件夹

TEMP/TMP- 暂时目录，能够随时被清理

获取LOCALAPPDATA/
APPDATA/USERPROFILE /ALLUSERPROFILE:

CString sPath; SHGetFolderPath( NULL, CSIDL_ LOCALAPPDATA/, NULL, 0, sPath.GetBuffer(MAX_PATH) ); sPath.ReleaseBuffer(); 类似还支持: CSIDL_LOCALAPPDATA /CSIDL_APPDATA/CSIDL_PROFILE(參考shlobj.h)

获取暂时文件夹TEMP/TMP:

// 获取暂时目录 CString sTempPath; ::GetTempPath(MAX_PATH, sTempPath.GetBuffer(MAX_PATH)); sTempPath.ReleaseBuffer(); CString sTempFile; // 获取暂时文件: 输入文件名称前缀。自己主动获得一个不反复的文件名称 ::GetTempFileName(sTempPath, _T(“MyPre_”), 0, sTempFile.GetBuffer(MAX_PATH)); sTempFile.ReleaseBuffer();
